PROBLEM TO BE SOLVED: To provide an agrochemical granule composition to give agrochemical granules which has hardness not causing collapse by vibrations on transportation and is quickly collapsed and scattered, when charged in water. SOLUTION: This agrochemical granule composition is characterized by containing a polymer obtained by graft-polymerizing vinyl pyrrolidone to polyvinyl alcohol. The agrochemical granule composition is preferably characterized by containing a polymer having a K value of 12 to 150 and obtained by graft-polymerizing vinyl pyrrolidone to polyvinyl alcohol having a polymerization degree of 100 to 4,000 and a saponification degree of 70 to 100 mol%. The polymer can be produced by compounding vinyl pyrrolidone to a polyvinyl alcohol solution and polymerizing using hydrogen peroxide, an organic peroxide or an azo compound as a polymerization initiator.
